JET coNDENsEB.

Application led January 11, 1922. Serial No. 528,519.

To all'whom t may concern:

Be it known that-we, WILLIAM R..VV1LsoN and ARTHUR P. BROCKLEBANK,citizens of the have invented certain new and useful Improvements in JetCondensers, of whichthe following is a specification, reference beinghad therein to the accompanying drawing.

Our invention relates to an apparatus for the condensation of exhauststeam, the particular class being that of jet condensers either of thebarometric type or of the low level jet type With which a centrifugalremoval pump is usually employed. One object We have in view among manythat might be mentioned .is to provide means for introducin thecondensing wat-er into the chamber o condensation by subdividing it intoa number of streams in such a manner that there may be a more thoroughcontact betweenthe condensing Water and the steam, and hence a quicker.and more effective condensation. The invention therefore may be saidto` consist essentially in the Vconstruction, arrangement andcombination of parts, and in numerous details and peculiarities thereof,substantially as will be hereinafter described and claimed.

In .the accompanying drawings illustrating our invention:

Figure 1 is a vertical section of our improved jet condenser, taken onthe line 1, 1, of Figure 2.

Figure 2 1s a horizontal sectional plan of the same, on the line 2, 2,of Figure 1.

Figure 3 is a horizontal detail section on .the line 3, 3, of Figure 1.

Figure 4 is an enlarged detail section on the line 4, 4, of Figure 2,and

Figure 5 is another enlarged detail section on ,the line 5, 5, of Figure2.

Similar characters of reference designate corresponding parts throughoutthe different figures of the drawing.

1 denotes the main cylindrical condenser shell containing the chamberof-condensa-- tion A. This shell is mounted on the tailpipe 2, fromwhich the water may be removed by a centrifugal or other pump, orv

tions.

Ex aust steam enters shell 1 through with Water all the time.

the side inlet 3, while the injection waters flow through pipe 5 andentera supply chamber 4 supported on the top of the condensing chamberA. The Water inlet 5 may be located at any desired point in the watersupply chamber, that is to say on any part of the same, and anywhererelatively to the shell and the steam inlet. The water chamber or boxwill probably be quite well filled The injection water passes fromchamber 4 into chamber A through the slotted bottom plate 8 of chamber4, as I shall presently describe in detail, and falls from chamber 4into and through the condensing chamber A in order that it maythoroughly commingle with and condense the Steam, the condensing waterand the condensed steam falling into and passing off through thetail-pipe 2 and its connections. The air and non-condensable vapors areremoved through the pipe or passage 13 at one side of the shell 1,formed etween the wall of the shell and asuspended plate 7,.said passagehaving an outlet 6 by which a connection is made with the vacuum or airremoval pump.

The bottom plate or tray 8 of the water chamber 4 is formed withopenings, slots, orifices, or passages, to permit the water to fallthrough into the condensing chamber A, and be split up into numerousparts, and in the present example of our invention these openings takethe form of elongated slots 9, preferably converging from the side ofthe shell where the exhaust steam inlet is located toward the air outlet6, like the ribs of a fan, so that the water may thus be introduced mostdirectly and surely through these outlets into the chamber A. It will benotedI that a considerable space of crescent shape is left at 17 betweenthe ends of these slots which are nearest the steam inlet and theadjacent wall ofthe Water chamber, so that there will be a correspondingspace at 15 in thechamber A between the ends of the sheets or streams ofwater'and the steam inlet 3, and wall of the shell. This space will belled with steam in large quantity which will ow and feed around to theends of the slots through the ends of the crescent shaped space 15, thuspassing along the sides of the shell from the widest to the narrowestparts of such space, so that an effective large distributing space forthe steam is verging in width from one end to the other,

the narrower end b being nearest air outlet 6 and the wider end a; beingnearest the exhaust inlet 3; and further each slotl on its top chamberside, or the side which first receives the water, is made flaring orwith l beveled edges or sides that extend a substantial .distancethrough the thickness of plate 8, while the lower discharge sides ofthese slots are made with parallel edges or surfaces, as shown at a1 inthe widest end of' the slot and at b1 in the narrowest end of- .theslot, see Figures 4 and 5. The wide receiving mouth of the slot enablesthe water to more quickly enter it, and the straight' verticalparallel-sided. discharge or outlet side permits a downward shootl ordrop of the water in a large voluminous sheet which has an extensivesurface exposure to come into contact with the steam which is to becondensed. The sectional views of Figures 4 and 5 indicate how the slots9 widen out from one end to the other, and also how the beveled inletside of the slot compares with the parallel-sided outlet edge. Theseradial slots ina series whose members are the longest in the middle andthe shortest near the sides, in combination with the steam distributingspace constitute an important feature.

In addition to the series of radiating slots 9 which cover substantiallythe whole area of plate 8, except the end part that covers the steamdistributing space 15, leaving between and around them only enough ofthe plate to preserve its stability and strength to carry the weight ofwater that lls the chamber 4, we find it convenient to further provideplate 8 with a few curved slots 10 arranged in one or more curved linesbetween the closely aggrouped narrower inner ends of slots 9 and the airoutlet members 13 and 6, and close up against the partition 7' thatforms the inner wall of air-outlet 13, said openings 10 however enteringthe condensation chamber A and not the air-passage 13., and being forthe purpose of introducing curved segments of condensing water justoutside of the air outlet 13. Through these slots 10 a blanket orcurtain of cold water falls transversely near the ends of the Isheetswhich drop through the slots 9 and this final curtain of rcold waterimparts a final cooling and condensing effect upon any steam leftuncondensed in passing the restl of the condensing water, so that at thepoint nearest the air outletvthe'air and uncondensable vapors will beseparated from the water, and will pass off at the point 14 into airoutlet pipe 13 and connection 6, while the vwater will fall downwardlythrough the shell and mingle with the other water passing out into thetail pipe. The ends of the slots 10 are separated more or less bypassages 16 which are at a different angle from the radial lanes betweenthe slots 9, and this causes the steam passing through these convergingradial lanes between the water sheets from slots 9 to attack thesegments of water falling through slots 10 diagonally and will not assdirectly midway through the openings 16, so that in this way the coldwater more effectually influences and condenses the steam, in the finalcondensing process, and in the final air-separating and cooling effect.The steam which passes through the radial or converging lanes betweenthe water sheets falling from slots 9 converges likewise and reduces involume as it flows towards the air outlet; corresponding thus to thereduced volume of water exposed to the steam.

The air-outlet 13, as already explained, is formed by the shell 1 and aninner curved plate or wall 7 whichprojects downwardly alongside of theshell and is secured atl its upper end by means of bolts 11 to thehorizontal plate 8, the open lower end of passage 13 being indicated at14 where the air and non-condensable vapors are drawn by' suction intothe outlet 13. It may be further noted that the crown of the waterchamber 4 is provided with onefor more covered hand openings 12, to giveaccess as required to the interior of the chamber.

The operation can be very briefly set forth. The exhaust steam `entersthe inlet opening 3 and there "fills'a-n'd flows around through lthespace 15 in the side of the con-- densation chamber A, there coming intocontact immediately with streams or sheets of water falling throughslots 9 from chamber 4. rlhese streams or sheets are the largest andhave the greatest volume where they fall through the widest ends ofopenings 9, (which wide ends are nearest steam inlet 3), and intovcontact with them the steam comes immediately upon entering the shell.As the quantity of steam reduces in volume, the sheets of condensingwater which will be encountered will be gradually diminishing in width,as the smaller portions of the slotsare approached, and the amount ofwater supplied through the narrower portions of the slots will beconstantly diminishing, so that by the time the steam reaches theentrance 14 into the air-with drawal member, the steam will havevirtually all been condensed, and the air and uncondensed vapors willreadily be drawn into the vacuum of the dry vacuum connection after theyhave been released from the steam' and water. The auxiliary .slots 10crossing the other slots 9 adjacent to the air outlet.

furnish important cross-streams at this point and assist in the finalcooling and disposal of air and uncondensable material.

Many changes may be made in the precise construction and combination ofthe various parts of our invention without exceeding the scope oftheclaims, particularly with reference to the number, size and character ofthe passages between the top water chamber and theondensing chamber forsubdividing the condensing water into a pluralityof sheets or streams,and We therefore reserve` the liberty of modifying and changing theexact details of construction and combination as much as may be foundnecessary to adapt the invention for practical use .in a great varietyof places for which it is suited.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:

1. In a jet condenser, the combination with a shell, having a steaminlet, and an air outlet, of an injection water inlet having a bottomprovided with a plurality of slots converging towards the air outletfrom a crescent shaped steamdistributing space located in the shell nearthe steam inlet and partially extending around the ends of the slots,said crescent shaped steam space being located opposite to a similarspace in the water chamber.

2. In a jet condenser, the combination with a shell having a steam inletand an air outlet, of an injection water chamber having a bottomprovided with a plurality of slots converging towards the air outlet,and an auxiliary transverse curved slot or slots adjacent to the airoutlet to deliver final cooling water.

3. In a jet condenser, the combination of a shell having a condensingchamber provided with a steam inlet, and an inner vertical wall oppositethe steam inlet and forming with the shell an interior air chamberreceiving the air escaping from the condensing water and the water ofcondensation, and having an air removal outlet, and an injection waterinlet mounted on the shell. and having a series of elongated slotsradiating from a point near the air chamber and widening therefrom tothe opposite end, so as to present the largest sheets of water at apoint nearest to the steam inlet, together with slots arrangedtransversely to the elongated slots.

4. In a jet condenser, the combination of a shell having a condensingchamber provided with a steam inlet, and an inner ver- -tical wallopposite the steam inlet and forming with the shell an interior airchamber receiving the air escaping from the condensing water and theWater of condensation, and having an air removal outlet, and aninjection water inlet mounted with the shell and having a plurality ofopenings or passages, each having beveled edges to provide a flaringmouth 0n the receiving side and a parallel-sided passage leading fromsuch mouth to the discharge side of the opening.

5. In a jet condenser, the combination of a shell having a condensingchamber provided with a steam inlet, and an inner Vertical wall oppositethe steam inlet and forming with the shell an interior air chamberreceiving the air escaping from the condensing Water and the water ofcondensation, and having an air removal outlet, and an injection Waterinlet mounted with the shell and having a series of elongated slotsradiating from a point near the air chamber and widening therefrom tothe opposite end, so as to present the largest sheets of Water at apointV nearest to the steam inlet, together with a series of openingsrunning cross-wise of said slots adjacent to the air chamber.
